ABSTRACT

A video textbook environment may provide video textbooks for students in various classes at various institutions. The video textbook environment may provide a web interface that displays videos and enables students to take notes regarding the videos. The student may request bookmarks be placed on a video. These bookmarks may be selected to return the video to the designated portion associated with the bookmark. The notes may be timestamped to correspond with a video counter value, such as where a bookmark is positioned. In this fashion, a student&#39;s notes may be associated with a given location in the bookmark. Notes may be aggregated for partitions of the video textbook. In particular, notes can be stored in a database a query may be issued to aggregate notes for a selected partition. The notes may then be displayed or downloaded to a user, such as a student.

BACKGROUND

Textbooks conventionally have been paper books that are bound and provided to students. These textbooks are organized into chapters and may include illustrations as well as text. Such textbooks may be cumbersome since many of them are heavy and difficult to transport. Moreover, such textbooks may be easily lost by students. Still further, such textbooks are limited in the content they convey to a user. Specifically, the content is typically limited to text and graphical images.

SUMMARY

In accordance with an exemplary embodiment, a method is performed by at least one processor of a computer video textbook environment. The method includes outputting a video as part of a web interface for a video textbook and a designated portion of the web interface. The video relates to a topic for the video textbook. A timestamp reflective of a location of the video is added to notes entered by a party regarding the video via a notes section of the web interface. The notes are stored with the timestamp in a storage. The notes are retrieved with the timestamp for display on the web interface. In response to the retrieving, the video is cued for output in the designated portion of the web interface starting at the timestamp. In addition, the notes are displayed on the web interface. The notes may include a user id of the party that is stored with the notes. Information that is indicative of the identity of the video may also be stored with the notes. The timestamp may be added responsive to an action of the party. One example of the action of the party is activation of the user interface element. The current time and date may be added to the notes before the notes are stored.

DETAILED DESCRIPTION

The exemplary embodiments herein provide a video textbook environment. The video textbook environment may be used to gain access to video textbooks. The video textbooks are akin to conventional paper textbooks but include the additional content of embedded videos as the primary vehicle for delivering content to users. The video textbook may be accessed by a computer and thus there is no need for a student to carry a heavy textbook and keep tabs on the whereabouts of the textbook. The video textbook environment may provide the video textbooks to multiple students for multiple classes at different educational institutions. The video textbook environment provides a mechanism for keeping track of the appropriate textbooks for each of the classes at respective institutions in which the video textbooks are used.

As will be described in more detail below, the video textbooks are logically partitioned into partitions, such as chapters. The chapters may be further divided into sections, and the sections may be further divided into lessons. Alternatively, different logical partitions may be applied to the material in a video textbook. The user may traverse the chapters in sequential order or may view only selective sections or lessons. The instructor of the class is given the option of selecting which chapters, sections and/or lessons are assigned to students in the class.

The student is given options via the user interface to watch videos on relevant topics and to take notes regarding the videos via the interface. These notes may be stored for subsequent retrieval. In some exemplary embodiments, the notes for different partitions may be aggregated and made available to the student. For example, the notes of a single chapter may be aggregated and made available to a student. Still further, notes taken for multiple chapters may be aggregated. This may be especially useful in preparing for tests that span chapters, such as midterm examination or final examinations.

In some exemplary embodiments, a student may bookmark a video at a given point in the video. The bookmark may be subsequently accessed to return to that point in the video. The bookmark may be represented by a user interface element, such as an icon. This allows a student to return to a portion of a video that is of interest after having previously watched the video.

In some exemplary embodiments, a student may timestamp their notes by selecting a user interface element. The timestamp represents a position in the video to which the notes relate. The timestamp may be manifest as a video counter or timer value. This allows a user to correlate the notes with the content in the video. This may be helpful when reviewing information for tests or for reinforcement of the lessons.

The video textbook environment may also provide facilities for an instructor of the class. The facilities may include the ability to post assignments, class materials and quizzes to be taken online by students. The instructor may also post test results or quiz results to the students via the video textbook environment. The video textbook environment may provide a roster of students for a given class.

The video textbook environment may also provide messaging capabilities, such as email messages, online chat or other communication mechanisms. This may allow the instructor to communicate with the students or for students to communicate with each other.

The embodiments described below relate to a distributed implementation in which the user interface is provided over a network such as the Internet. Nevertheless, it should be appreciated that in some embodiments the video textbook environment may be provided locally on a user's machine.

FIG. 1 shows an example of an initial screen that may be displayed as part of the interface to a student by the video text book environment. The initial screen 100 includes a location 102 for entering an institutional email address and a “Get Started” button 104 for passing the email address on to the video textbook environment. The students institutional email address is used as an identifier. The user may configure his/her account, including choosing a particular user name or password.

These concepts all relate in some manner to hearing.

FIG. 8 shows an example where the interface 800 is displaying a video 802 relating to hearing under chapter 19, section 26. The video has a play button 804 as well as a video timeline 806. The darkened portion 808 indicates how much of the video has played and the current position within the video. The timer in this example case is currently at five (00:05) seconds, and the video is one minute and thirty seconds long. The interface 800 shown in FIG. 8 has a transcript button 810 which may cause the transcript of the video to be displayed. The interface 800 also includes a “take notes” button 812 which may be activated so that the notes taking section 814 open and may be used to enter notes.

The notes shown in the notes taking section 814 include an indication of the video and also an indication of chapter and section. Thus, the notes shown in FIG. 8 designate that the notes relate to chapter 19, section 26.

The notes may also be timestamped. The timestamping in this case entails specifying a point in the video to which the notes relate. In this example case, a timestamp of five seconds is provided as the notes relate to the video at the five second mark. A user interface element, such an icon may be activated in order to add the timestamp to the notes.

FIG. 9 provides a flowchart of the steps that are performed for such timestamping. Initially the video is played (step 902). The user then activates the user interface element (step 904). As is discussed above, the user interface element may take different forms, such as an icon, a menu item, etc. The timestamp is then added to the notes in step 906. Additional information may be added by the video textbook environment to the notes. For example, the video textbook environment may add the date and time at which the notes were taken (step 908). This step is not obligatory and may be optional in some embodiments. These notes are then saved for subsequent access. The notes may be saved in persistent storage. In example shown in FIG. 9, the notes are added to a database (step 910), which will be described in more detail below.

The video textbook environment allows the user to bookmark a position in a video. This bookmark may then be activated to return to the specified video location. FIG. 10 shows a flowchart 1000 illustrating the steps performed for such bookmarks. Initially, the party requests a bookmark (step 1002). This request may take different forms, such as activating a bookmark user interface element, making a menu selection or performing an action, such as a mouse click or a designated keystroke. An icon is then added to the video timeline in exemplary embodiments (step 1004).

FIG. 11 shows an example of a video timeline in which icons 1102 have been added to designate where bookmarks have been positioned. Interface 1100 shown in FIG. 11 also includes a bookmark icon 1106 that may be selected to create a new bookmark. This same bookmark icon 1106 may be used to create a times stamp in notes.

As shown in FIG. 10, the resulting bookmark may be subsequently used by the user to return to the specified video position. In the example shown in FIG. 10, the icon, such as one of icons 1102 in FIG. 11, is selected in step 1006. The video is then updated to the position of the icon (step 1008). This may be realized by sending appropriate commands to the video or media player.

FIG. 11 also illustrates that a partial portion of the table of contents may be displayed in a scrollable form in some embodiments. In this instance, the chapters of the video textbook are displayed in a scrollable list where a given chapter may be selected to expand to illustrate the sections of the chapter. A button 1110 may be provided to display the full table of contents.

The user may also have control over the speed at which the video is displayed. In an example shown in FIG. 12, the interface 1200 includes a video 1202 that has a speed list 1204 that may be expanded to illustrate the speed options.
